regulator: fixed: Rely on the core freeing the enable GPIO

[ Upstream commit 79a45ddcdbba330f5139c7c7ff7042d69cf147b2 ]

In order to simplify ownership rules for enable GPIOs supplied by drivers
regulator_register() always takes ownership of them, even if it ends up
failing for some other reason. We therefore should not free the GPIO if
registration fails but just let the core worry about things.
